GM Genius 90 needs fixing

[ChrissieL]

Hi, unfortunately the white plug (sits inside the case) where you plug in the sensor lead to the GM motherboard has totally snapped off I know I need to send this back to Graupner to fix (via Schumacher) but trying to decide if it is fixable and therefore worth the cost of sending it to them or just to buy another esc (hobbywing for example).

Has anything similar happened to anyone or indeed have to send their GM to get repaired? Looking any indication of cost, inc postage.

Thanks

Chris
